4 Claims- (01 139-13) This invention relates to looms such as may a fixed spindle or onto a" pole or mandrel which I may be fed through the loom in synchronism with its weaving mechanism,'the apparatus be ing readily convertible from one use to the other. Another purpose of the invention is to provide in a loom structure means for conveying the warp threads through the structureat a determinate speed and a tensioning means for the warp thread driven in synchronism' with the thread conveying means to eliminate breakage of thewarpthreads.

Another purpose of the invention is to provide heddles so constructed asfto carry the warp threads clear of the shuttle in leading them to the spindle or to the pole or mandrel to which they are applied. I

The foregoing and other purposes of the invention are obtained in .the loom 'structure illustrated in the accompanying drawings and described below. It is to be understood that the invention is not limitedto the specific form thereof shown and described; ,Of the accompanying drawings:

Figure 2 is a perspective view-of the apparatus looking at it'from' anangle' toward the delivery end of the machine when weaving ona pole or mandrel.

Figure 3 is a vertical section: through the weavlng unit. I

Figure 4 is'anelevation of the feeding unit at the delivery end thereof." I

Figure 5 is an end elevation of the tube-conveying mechanism atthe delivery. endcof the loom when tube is being woven on afixed spindle. Figure 6 is a similar view at the delivery end of the loom showing the device When adapted for weaving on a pole or mandrel.

Referring to the drawings, thenumeral In indicates a suitable frame structure which may The loom structure comprises a weaving unit indicated generally by the numeral l l and which may be of'the general structure and design of the weaving unit I0 shown in the loom apparatus disclosed in a co-pending application of the present inventor, Serial No. 350,230, filed August 3, 1940. It will be sufficient, it is believed, for the present application to limit its description of the weaving unit H to features thereof which are not shown and described in the co-pending application referred to; i

For supplying the warp threadto the unit II a rack structure may be arranged under frame H] as indicated generally at l2 on which may be mounted creels l3, I3 of warp thread which may sion roll M of a knowntype and about which" the warp threads may be wound and extended therefrom to the weaving unit II in the known I manner as illustrated.

Tension roll I may have the usual adjustable brake l4aassociated therewith for determining the tension to be maintained on the warp threads,"

In the loom structure in the above referred to co-pending application the warp threads are guided to the pole or mandrel on which the tube or hose is being formed in such a way as to bear upon the shuttle. In accordance with the present construction the threadis extended to' elongated guiding tubes l5, .l5 associated with the usual cam operated sliders or heddles 16, so that the thread is carried clear of theshuttle indicated at IT, the thread extending'from the tube 15' to the spindle I8 (see Figure 3) to beinterwoven with thread supplied by the shuttle which is guided onto the spindle I8 (Figure 3) or mandrel'M (Figure 2) by Spreaders l9, l9 whichcorrespond in general to the'spreaders indicated at the delivery end of the weaving unit II in the bore Ila as by bushing l8a.

The sliders or heddles [6 may be operated by the cam mechanism shownin Figure 3 which corresponds in every substantial respect to that operating the sliders or heddles in the loom unit shown in the co-pending applicationcreferred to.

To.adapt the loom structure for conversion to use on poles or mandrels on which the tube or hose maybe Woven, there is arranged at the feed end of the machine a pair of feed rollers 2D, 20, the upper one of, which may be mounted on the bracket 2| hinged at 2 2 on a bracket 23 which ing along the top ,of frame in, and mounted in suitable bearings at 28, 28, the suitable gearing between shaft 21 and the cross shaft being housed at 29.

In order to drive the tension roll M in synchronism with the speed of the warp threads as j p of the tube will merel cause hinging action of determined by the speed of the feeding drum to be described, it may be mountedon the shaft-- mounted in bearings such as indicated at3l and having thereon a pulley 32 driven by a belt 33 from a pulley (not shown) on the cross shaft which is housed at 26.

The drive motor for the unit 1 I may drive the a unit through suitable change-speed gearing (not shown) and describedin ,theaforesaid vco-pending applicationand through the pulle arrangement or otherwise, housedat- 34, the drive motor being indicated at 35. Shaft 21 is arranged to be driven in synchronism with the weaving unit H from motor 35 throughthe change-speed gearing and shaft 36 and gearing 31.

At the delivery end of the machine thereis a feeding drum 38 about which the tubing. may be wound as it issues from the weavin apparatus II, the feeding drum 38 being drivenfrom shaft 21 through suitable gearing housed at 29a and 29b (see Figure 2) and as best illustrated: at Figure 5. Shaft21 may havea gear 39 thereon meshed with a gear 40 for driving asprocket at 4| over which'is trained a sprocket chain 42- drivinga sprocket 43 on shaft of drum 38 which may be mounted on bracket 44. Gearings 39 and 4|! may also drive the-sprocket-45 through suitable chain and sprocket mechanism not shown but housed at 29b to drive a feed roller 46. Associated with the feed roller 46 is the co-operating feed roller 41 mounted ,on a bracket 48 which is hinge-d at 49 and has weights 48a, 48a thereon for applyin determinatepressure ;of roller 41 on woven tubing indicated at T passing between the feed rollers 46 and 41. Associated with the feeding drum 38 isa deflector 50 for causing windings on the feeding drum38 to be deflected onto-a tapered portion 38a on the periphery of feeding drum 38 from whence the tubing may be trained to pass between the rollers 46 and 4.1. The defiector50 may bemounted on an arm 5| hinged at 52 whichmay be weighted'as indicated at 53 tocontrol the pressure of deflector 50 on the'periphery of feedin drum 38.

When it is desired to convert the apparatus to weaving a tube upona pole or mandrel indicated at M in Figures 2 and 6, the arm 5| carryingdefiector 5|lmay be removed fromthe hinge mounting at 52 and may be replacedby armyl iilcarrying pressure roll 41 which may beremoved from its hinge mounting at 49 and mounted ,on the. hinge at 52. .Thus ,a pole or mandrel M may be sup ported to be .fed through the loom. bypassing between thefeed. rollers 20 at thefeed-end of the machine and between the feedin drum Y38 and the feed roller 41 at the delivery end of the machine as shown inFigures 2 and 6..

In the operation of thejloom for weaving on the fixed spindlelfi as indicated in Figures 1, 3, 5, the warp threads I 3 are fed up over the tension roll M which is driven by belt 32 at a slightly higher speed than the feeding drum38 and the feed rolls 46 and 41 and which has tension applied bythe brake |4a so that the warp threads may be passed through the loom by the substantially synchronized speed of the tension roll M with the feeding drum 38 and feed rollers 46 and 41, thus preventing breakage of the Warp threads. As the woven tube passes from the delivery unit II, it passes to the feeding drum 38 and around the feeding drum several times and finally to'the feed rollers 46 and 41 from between which it issues from the loom. Due to the hinge action of the deflector arm 5| and of the arm 48 any knots or imperfections or/and variations in the thickness ingzfree passage of the tubing from the machine.

When it is desired to convert the machine from vweaving on vthe fixed spindle l8 to weaving on a mandrel such as M, the bushing |8a with spindle I8 is removed and the mandrel will be fed through the loom as-indicatecl in Figures 2 and '6, being passed betweenthe feed rollers .20 through bore Hit of unit II and between the feeding drum 38 and feed roller .41 which propel the mandrel throughtheloom in ,synchronism with the weaving unit H. In making a conversionvof the apparatus to use for weaving on mandrel M, it is merely necessary to remove the hinge bracket 5| (see Figure 5) and replace it by the hinge bracket 48, the roller 41-thereon, in -cooperation with the feeding drum 38 being aligned with the feed rollers 20. 'The pick of the woof thread applied to the mandrel 'M, of course-will be determined by thespeed at which the mandrel M is fed through the apparatus.

In all uses of the apparatus, the guiding tubes IS on the slider or.heddle l6, which carry the warp threads, guide the warp threads. either to the spindlelB, as indicated in FigureB, or to the pole or mandrelM'in such a way as to .clear the including a slip driving connection. to said tension roller. a
